Epocrates has fixed an issue in older versions of its mobile application regarding how login credentials were transmitted. In addition to releasing the new versions in the App Store and on Google Play, Epocrates is proactively communicating to the Epocrates community what happened, and encouraging users to update to the latest version, including having direct communications with users who appear not to have updated. Importantly, there is no indication that any user’s Epocrates credentials were compromised, but as a security precaution we are recommending that users also reset their passwords once they update the app.
